I just recently switched from gmail to Mailfence with a custom domain, and I’m pretty happy thus far. I looked into it for a while trying to find the best option, and Mailfence turned out the best for me. Tuta was too locked down for me and Mailbox just rubbed me the wrong way. Mailbox has had a known major security issue with custom domains for literally 7 years now and still has yet to addressed it, their webmail is extremely slow and buggy (would switch to German randomly), they don’t encrypt messages at rest (which to be fair isn’t too important, but a lot of other services still do it), and I’ve seen multiple reports of their support being sub-par. I feel like they’re probably still fine, but I just feel more confident in Mailfence.
